Overtime,\nprofiles are captured on various machines and it becomes hard to track\nwhat was recorded, on what machine and when.\n\nThis patch provides a way to solve this by extending the perf.data file\nwith basic information about the host machine. To add those extensions,\nwe leverage the feature bits capabilities of the perf.data format. The\nchange is backward compatible with existing perf.data files.\n\nWe define the following useful new extensions:\n - HEADER_HOSTNAME: the hostname\n - HEADER_OSRELEASE: the kernel release number\n - HEADER_ARCH: the hw architecture\n - HEADER_CPUDESC: generic CPU description\n - HEADER_NRCPUS: number of online/avail cpus\n - HEADER_CMDLINE: perf command line\n - HEADER_VERSION: perf version\n - HEADER_TOPOLOGY: cpu topology\n - HEADER_EVENT_DESC: full event description (attrs)\n - HEADER_CPUID: easy-to-parse low level CPU identication\n\nThe small granularity for the entries is to make it easier to extend\nwithout breaking backward compatiblity. Many entries are provided as\nASCII strings.\n\nPerf report/script have been modified to print the basic information as\neasy-to-parse ASCII strings. Extended information about CPU and NUMA\ntopology may be requested with the -I option.\n\nThanks to David Ahern for reviewing and testing the many versions of\nthis patch.\n\n $ perf report --stdio\n # \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n # captured on : Mon Sep 26 15:22:14 2011\n # hostname : quad\n # os release : 3.1.0-rc4-tip\n # perf version : 3.1.0-rc4\n # arch : x86_64\n # nrcpus online : 4\n # nrcpus avail : 4\n # cpudesc : Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz\n # cpuid : GenuineIntel,6,15,11\n # total memory : 8105360 kB\n # cmdline : /home/eranian/perfmon/official/tip/build/tools/perf/perf record date\n # event : name \u003d cycles, type \u003d 0, config \u003d 0x0, config1 \u003d 0x0, config2 \u003d 0x0, excl_usr \u003d 0, excl_kern \u003d 0, id \u003d { 29, 30, 31,\n # HEADER_CPU_TOPOLOGY info available, use -I to display\n # HEADER_NUMA_TOPOLOGY info available, use -I to display\n # \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n #\n ...\n\n $ perf report --stdio -I\n # \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n # captured on : Mon Sep 26 15:22:14 2011\n # hostname : quad\n # os release : 3.1.0-rc4-tip\n # perf version : 3.1.0-rc4\n # arch : x86_64\n # nrcpus online : 4\n # nrcpus avail : 4\n # cpudesc : Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz\n # cpuid : GenuineIntel,6,15,11\n # total memory : 8105360 kB\n # cmdline : /home/eranian/perfmon/official/tip/build/tools/perf/perf record date\n # event : name \u003d cycles, type \u003d 0, config \u003d 0x0, config1 \u003d 0x0, config2 \u003d 0x0, excl_usr \u003d 0, excl_kern \u003d 0, id \u003d { 29, 30, 31,\n # sibling cores : 0-3\n # sibling threads : 0\n # sibling threads : 1\n # sibling threads : 2\n # sibling threads : 3\n # node0 meminfo : total \u003d 8320608 kB, free \u003d 7571024 kB\n # node0 cpu list : 0-3\n # \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n #\n ...\n\nReviewed-by: David Ahern \u003cdsahern@gmail.com\u003e\nTested-by: David Ahern \u003cdsahern@gmail.com\u003e\nCc: David Ahern \u003cdsahern@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Robert Richter \u003crobert.richter@amd.com\u003e\nCc: Andi Kleen \u003cak@linux.intel.com\u003e\nLink: http://lkml.kernel.org/r/20110930134040.GA5575@quad\nSigned-off-by: Stephane Eranian \u003ceranian@google.com\u003e\n[ committer notes: Use --show-info in the tools as was in the docs, rename\n perf_header_fprintf_info to perf_file_section__fprintf_info, fixup\n conflict with f69b64f7 \"perf: Support setting the disassembler style\" ]\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "5d67be97f8903d05ce53597fb5f3bc25a45e8026", "tree": "5ce8c2407d50570d7fee79b9c7f24e8eb89384b4", "parents": [ "9f8b6a6cf0ee78de87ebe1e87f54bec1c1741ef7" ], "author": { "name": "Anton Blanchard", "email": "anton@samba.org", "time": "Mon Jul 04 21:57:50 2011 +1000" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Jul 05 10:44:44 2011 +0200" }, "message": "perf report/annotate/script: Add option to specify a CPU range\n\nAdd an option to perf report/annotate/script to specify which\nCPUs to operate on.

-0600" }, "message": "perf trace: live-mode command-line cleanup\n\nThis patch attempts to make the perf trace command-line for live-mode\ncommands more user-friendly and consistent with other perf commands.\n\nThe main change it makes is to allow \u003ccommands\u003e to be run as part of\nperf trace live-mode commands, as other perf commands do, instead of\nthe system-wide traces they\u0027re currently hard-coded to by the shell\nscripts.\n\nWith this patch, the following live-mode trace now works as expected:\n\n $ perf trace rw-by-pid ls -al\n\nThe previous system-wide behavior for this command would still be\navailable by explicitly specifying -a:\n\n $ perf trace rw-by-pid -a ls -al\n\nand if no \u003ccommand\u003e is specified, the output is also system-wide:\n\n $ perf trace rw-by-pid\n\nBecause live-mode requires both record and report steps to be invoked,\nit isn\u0027t always possible to know which args to send to the report and\nwhich to send to the record steps - mainly this is the case for report\nscripts with optional args - in those cases it would be necessary to\nuse separate \u0027perf trace record\u0027 and \u0027perf trace report\u0027 steps.\n\nFor example:\n\n $ perf trace syscall-counts ls\n\nHere we can\u0027t decide whether ls should be passed as a param to the\nsyscall-counts script or whether we should invoke ls as a \u003ccommand\u003e.\nIn these cases, we just say that we\u0027ll ignore optional script params\nand always interpret the extra arguments as a \u003ccommand\u003e.\n\nIf the user instead wants the other interpretation, that can be\naccomplished by using separate record and report commands explicitly:\n\n $ perf trace record syscall-counts\n $ perf trace report syscall-counts ls\n\nSo the rules that this patch implements, which seem to make the most\nintuitive sense for live-mode commands:\n\n- for commands with optional args and commands with no args, no args\n are sent to the report script, all are sent to the record step\n\n- for \u0027top\u0027 commands i.e. that end with \u0027top\u0027, \u003ccommands\u003e can\u0027t be\n used - all extra args are send to the report script as params\n\n- for commands with required args, the n required args are taken to be\n the first n args after the script name and sent to the report\n script, and the rest are sent to the record step\n\nSigned-off-by: Tom Zanussi \u003ctom.zanussi@linux.intel.com\u003e\nAcked-by: Arnaldo Carvalho de Melo \u003cacme@ghostprotocols.net\u003e\n" }, { "commit":

\"hists\" methods, as they manipulate only struct hists\nmembers, not touching anything in the other perf_session members.\n\nOther optimizations, such as calculating the maximum lenght of a symbol\nname present in an hists instance will be possible as we add them,\navoiding a re-traversal just for finding that information.\n\nThe rationale for the name \"hists\" to replace \"event_stat_id\" is that we\nmay have multiple sets of hists for the same event_stat id, as, for\ninstance, the \u0027perf diff\u0027 tool has, so event stat id is not what\ncharacterizes what this

The\nspecs can be used either as prefixes or extensions.\n\nIf [language spec:] is used, the script is taken as a script of\nthe matching language regardless of any extension it might have.\n If [language spec:] is not used, [.ext] is used to look up the\nlanguage it corresponds to. Language specs are case\ninsensitive.\n\ne.g. Perl scripts can be specified in the following ways:\n\nPerl:scriptname\npl:scriptname.py # extension ignored\nPL:scriptname\nscriptname.pl\nscriptname.perl\n\nThe -g [language spec] option gives users an easy starting point\nfor writing scripts in the specified language. Scripting\nsupport for a particular language can implement a\ngenerate_script() scripting op that outputs an empty (or\nnear-empty) set of handlers for all the events contained in a\ngiven perf.data trace file - this option gives users a direct\nway to access that.\n\nAdding support for a scripting language\n---------------------------------------\n\nThe main thing that needs to be done do add support for a new\nlanguage is to implement the scripting_ops interface:\n\nIt consists of the following four functions:\n\n start_script()\n stop_script()\n process_event()\n generate_script()\n\nstart_script() is called before any events are processed, and is\nmeant to give the scripting language support an opportunity to\nset things up to receive events e.g. create and initialize an\ninstance of a language interpreter.\n\nstop_script() is called after all events are processed, and is\nmeant to give the scripting language support an opportunity to\nclean up e.g. destroy the interpreter instance, etc.\n\nprocess_event() is called once for each event and takes as its\nmain parameter a pointer to the binary trace event record to be\nprocessed. The implementation is responsible for picking out the\nbinary fields from the event record and sending them to the\nscript handler function associated with that event e.g. a\nfunction derived from the event name it\u0027s meant to handle e.g.\n\u0027sched::sched_switch()\u0027. The \u0027format\u0027 information for trace\nevents can be used to parse the binary data and map it into a\nform usable by a given scripting language; see the Perl\nimplemention in subsequent patches for one possible way to\nleverage the existing trace format parsing code in perf and map\nthat info into specific scripting language types.\n\ngenerate_script() should generate a ready-to-run script for the\ncurrent set of events in the trace, preferably with bodies that\nprint out every field for each event. Again, look at the Perl\nimplementation for clues as to how that can be done. This is an\noptional, but very useful op.\n\nSupport for a given language should also add a language-specific\nsetup function and call it from setup_scripting(). The\nlanguage-specific setup function associates the the scripting\nops for that language with one or more \u0027language specifiers\u0027\n(see below) using script_spec_register(). When a script name is\nspecified on the command line, the scripting ops associated with\nthe specified language are used to instantiate and use the\nappropriate interpreter to process the trace stream.\n\nIn general, it should be relatively easy to add support for a\nnew language, especially if the language implementation supports\nan interface allowing an interpreter to be \u0027embedded\u0027 inside\nanother program (in this case the containing program will be\n\u0027perf trace\u0027). If so, it should be relatively straightforward to\ntranslate trace events into invocations of user-defined script\nfunctions where e.g. the function name corresponds to the event\ntype and the function parameters correspond to the event fields.\n The event and field type information exported by the event\ntracing infrastructure (via the event \u0027format\u0027 files) should be\nenough to parse and send any piece of trace data to the user\nscript. The easiest way to see how this can be done would be to\nlook at the Perl implementation contained in\nperf/util/trace-event-perl.c/.h.\n\nThere are a couple of other things that aren\u0027t covered by the\nscripting_ops or setup interface and are technically optional,\nbut should be implemented if possible. One of these is support\nfor \u0027flag\u0027 and \u0027symbolic\u0027 fields e.g. being able to use more\nhuman-readable values such as \u0027GFP_KERNEL\u0027 or\nHI/BLOCK_IOPOLL/TASKLET in place of raw flag values. See the\nPerl implementation to see how this can be done. The other thing\nis support for \u0027calling back\u0027 into the perf executable to access\ne.g. uncommon fields not passed by default into handler\nfunctions, or any metadata the implementation might want to make\navailable to users via the language interface. Again, see the\nPerl implementation for examples.\n\nSigned-off-by: Tom Zanussi \u003ctzanussi@gmail.com\u003e\nCc: fweisbec@gmail.com\nCc: rostedt@goodmis.org\nCc: anton@samba.org\nCc:

With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant. (Also, defconfigs were not touched to\nkeep the size down.)\n\nThis patch has been generated via the following script:\n\n FILES\u003d$(find * -type f | grep -vE \u0027oprofile|[^K]config\u0027)\n\n sed -i \\\n -e \u0027s/PERF_EVENT_/PERF_RECORD_/g\u0027 \\\n -e \u0027s/PERF_COUNTER/PERF_EVENT/g\u0027 \\\n -e \u0027s/perf_counter/perf_event/g\u0027 \\\n -e \u0027s/nb_counters/nb_events/g\u0027 \\\n -e \u0027s/swcounter/swevent/g\u0027 \\\n -e \u0027s/tpcounter_event/tp_event/g\u0027 \\\n $FILES\n\n for N in $(find . -name perf_counter.[ch]); do\n M\u003d$(echo $N | sed \u0027s/perf_counter/perf_event/g\u0027)\n mv $N $M\n done\n\n FILES\u003d$(find . -name perf_event.*)\n\n sed -i \\\n -e \u0027s/COUNTER_MASK/REG_MASK/g\u0027 \\\n -e \u0027s/COUNTER/EVENT/g\u0027 \\\n -e \u0027s/\\\u003cevent\\\u003e/event_id/g\u0027 \\\n -e \u0027s/counter/event/g\u0027 \\\n -e \u0027s/Counter/Event/g\u0027 \\\n $FILES\n\n... to keep it as correct as possible. This script can also be\nused by anyone who has pending perfcounters patches - it converts\na Linux kernel tree over to the new naming. We tried to time this\nchange to the point in time where the amount of pending patches\nis the smallest: the end of the merge window.\n\nNamespace clashes were fixed up in a preparatory patch - and some\nstylistic fallout will be fixed up in a subsequent patch.\n\n( NOTE: \u0027counters\u0027 are still the proper terminology when we deal\n with hardware registers - and these sed scripts are a bit\n over-eager in renaming them. I\u0027ve undone some of that, but\n in case there\u0027s something left where \u0027counter\u0027 would be\n better than \u0027event\u0027 we can undo that on an individual basis\n instead of touching an otherwise nicely automated patch. )\n\nSuggested-by: Stephane Eranian \u003ceranian@google.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nReviewed-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: \"David S.
